DISCLAIMER; do NOT point this at people, and or small animals. As for it will cause injury to the first, and kill the latter.

Ok, so the bolt didn't stick in the cardboard, but it did make that hole, and all the other holes in that box. (Video at end shows it in action) This is just something I came up with when I was messing around with rubberband gun ideas.

Features a pistol grip and detachable stock.

Stock can be attached by the black pins shown.

The design is really simple, and the best part is it work very well.

As you can see, the rubberbands actually bend my technic beams, Just like a real crossbow would.

The bolt I designed it to shoot is show in this picture. The interesting part of this build was trying to make the Technic beams look good in an even number scale.

Bolt shown loaded.

This is the firing mechanism/trigger, you can't get much simpler than this.

Ok, so this part might be lame, but I made a "hidden" blade that can detach. I actually designed it as a grip and thought, that it would look good as a detachable dagger.

Great! i love this! I think this would be a good starter project for someone wanting to build other working guns! I love how hard it shoots! Great build! The video really helps show the raw power of it! 5/5 By the way, ill probly post my f-14 V2 today (im so excited)

@jebberb Yah, go ahead, it shouldn't be that hard to replicate. Thanks to everyone for commenting! Hey and Jon, I can't wait for your f-14. I'm also excited to see your trial truck.
